Hi Tim, Thank you very much - that has helped - however I discovered that the problem still exists if I have an include within an include - ie.
I have an include called this <jsp:include page="navmenu.jsp" flush="false"> Inside that include I have another include also with flush set to false - and I still get a blank page - however if I remove the includes within the include then the exception is visible. Any ideas on this?
